前几篇文章记录的都是iOS下基于FFmpeg的多媒体程序。本文记录一个IOS下自带的视频播放器。相比于移植FFmpeg来说,IOS自带的多媒体框架播放视频要简单很多——只需要调用几个接口就可以了。
源代码
项目的源代码位于ViewController.m文件中,内容如下所示。
-
- #import "ViewController.h"
- #import <MediaPlayer/MediaPlayer.h>
-
- @interface ViewController ()
-
- @property (nonatomic,strong) MPMoviePlayerController *moviePlayer;
-
- @end
-
- @implementation ViewController
-
- - (void)viewDidLoad {
- [super viewDidLoad];
-
-
- [self.moviePlayer play];
-
- [self addNotification];
-
- }
-
- -(void)dealloc{
-
- [[NSNotificationCenter defaultCenter] removeObserver:self];
- }
-
-
- -(MPMoviePlayerController *)moviePlayer{
- if (!_moviePlayer) {
- NSString *urlStr=[[[NSBundle mainBundle]resourcePath] stringByAppendingPathComponent:@"resource.bundle/war3end.mp4"];
- NSURL *url=[NSURL fileURLWithPath:urlStr];
- _moviePlayer=[[MPMoviePlayerController alloc]initWithContentURL:url];
- _moviePlayer.view.frame=self.view.bounds;
- _moviePlayer.view.autoresizingMask=UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight;
- [self.view addSubview:_moviePlayer.view];
- }
- return _moviePlayer;
- }
-
- -(void)addNotification{
- NSNotificationCenter *notificationCenter=[NSNotificationCenter defaultCenter];
- [notificationCenter addObserver:self selector:@selector(mediaPlayerPlaybackStateChange:) name:MPMoviePlayerPlaybackStateDidChangeNotification object:self.moviePlayer];
- [notificationCenter addObserver:self selector:@selector(mediaPlayerPlaybackFinished:) name:MPMoviePlayerPlaybackDidFinishNotification object:self.moviePlayer];
-
- }
-
- -(void)mediaPlayerPlaybackStateChange:(NSNotification *)notification{
- switch (self.moviePlayer.playbackState) {
- case MPMoviePlaybackStatePlaying:
- NSLog(@"正在播放...");
- break;
- case MPMoviePlaybackStatePaused:
- NSLog(@"暂停播放.");
- break;
- case MPMoviePlaybackStateStopped:
- NSLog(@"停止播放.");
- break;
- default:
- NSLog(@"播放状态:%li",self.moviePlayer.playbackState);
- break;
- }
- }
-
- -(void)mediaPlayerPlaybackFinished:(NSNotification *)notification{
- NSLog(@"播放完成.%li",self.moviePlayer.playbackState);
- }
-
-
-
-
- - (void)didReceiveMemoryWarning {
- [super didReceiveMemoryWarning];
-
- }
-
- @end
运行结果
App在手机上运行后的结果如下图所示。程序运行后,会自动播放resource.bundle中的war3end.mp4文件。
